Difficulty stopping timer during lap swimming on Apple Watch 10 Ultra

Thank you for your reply. I did see this solution in another discussion and tried it recently. It seemed to lock and close down the watch screen and then I had to re-enter password to open watch again. The timer was still going. It seemed to activate other watch responses other than pause workout. I have now tried this solution again while activating a pool swim out of the water and it does seem to work provided I press Digital Crown and side button lightly and evenly. I will try it again in the water today and hopefully it will work. Thank you for your help.

I presume you are a swimmer and this solution is working for you on a similar watch?
